Application filed March 9, 1914. Serial No. 823,538.

To all whom it may concern Be it known that T, NOAH citizen of theUnited States, and a resident of the city of New York, borough ofBrooklyn, in the county of Kings and State of 150W York, have invented anew and Improi'ed Tchiclo-llheel, of which the following is a full,clear, and exact description.

i-tmong the principal objects which the present invention has in vieware: to maiir tain the alinement of separately opera-ting elements oi"the wheel; to minimize the friction between the relatively moving parts;and to strengthen and simplify the construction.

In the drawings, Figure l is a side view of a wheel constructed andarranged in accordance with the present invention, the face plate ofsaid wheel being removed; Fig. is a vertical section, on an enlar 'edscale, taken as on the line 2-2- in Fig. 1; Fig. 2*

. is a detail *iew, on an enlarged scale, of a provided; Fig. 7 is adetail view, showing a fragment of one of the roller rimstFig. 8 is a.cross section on an enlarged scale, taken on the line 88 in Fig. 1; Fig.9 is a detail view showing a fragment of one of the tracks provided forthe bearing rollers, a portion of the fragment being cut away to show insection the construction thereof; Fig. 10 is a cross section, on anenlarged scale. taken on the line101O in Fig. 1,

,. showing a fragment of the outer track for invention is mounted on anaxle 20 extending the bearing rollers; Fig. 11 is a detail View inperspective, of framing member forming one of the curved segments withwhich the wheeis provided; Fig. 12 is a detail view in perspective, ofone of the filling members for the framing members shown in Fig. 11. v

As seen in Fig. 20f the drawings, a wheel constructed in accordance withthe present from a steering knuckle 21 of conventional form. The axleblock 22 of the present wheel is provided with a journal bearing 23 toslip over said axle, and is held non-rota-J tively thereon by a key 24,which in service GORNFIELD, a

extends over the hub 20 and rests in slots opening into the journalbearing 23 at the outer end of said block. In service, said block andkey are held by a nut 26, which is locked by a cotter pin 27 on thethreaded end of said axle.

The hub proper of the present wheel is primarily formed by the cheekplates 28 and hollow segments formed by a plurality of framing members29 and their filling members 30. The filling members are each providedwith edge flanges, one of said flanges being circular, and the otherflange being straight, to produce a truss-like construction. When two ofthe filling members oppositely disposed are backed each against theother, they are structurally united by rivets 31' to reinforce thearch-like construction of the framing members 29. The framing members 29are held in position by bolts 32, which are extended throughperforations formed in the plates 28, and through perforations 33 formedin both the framing members 29 and the filling members 30. The. threadedends of the bolts 32 engage the threads of tapped thimbles 34;, saidthimbles being employed in part to maintain the spaced relation of saidhollow segments, said spaces being provided to receive and guide theextension arms 35 and 36 of the axle block 22. i

As seen best in Figs. 11 and 12, the ends of the framing members 29 andthe filling members 80 are cut away on lines substantially radial to thecompleted wheel. The radial surfaces thus produced bear against cornerbl0cks'87, the intermediate exposed surfaces whereof are curved to matchthe curved flanges of the framing members 29.- The corner blocks 37 areeach provided with. a projection 38 to extend between channel trackrings 39, to assist in maintaining the alinement thereof. The rings 39,being thus lieldinteriorly, are held exteriorly by the cheek plates 28,the bolts 32 and 40 performing this office. The bolts L0 pass throughperforations disposed lengthwise in the blocks 37 and in cups 41, whichare seated in holes provided therefor in the cheek plates 28, as bestseenin Fig. 4: of the drawings. The bolts 4-0 are tightened by nuts 42.The heads of said bolts 40 and the nuts 42 are arranged to sink withinthe cups 41. The rings 39 are further held in alinement by an annularflange 43, with which each ring is provided. The, flange 418, as shownbest in Fig. 8 of the drawings, ex

rob

bers 36.

tends between the outer and curved flanges of the members 29, and restsfirmly upon the outer and curved flanges of the filling mem- Tt will beunderstood that the flange 43 may be integrally or rigidly formed with,or mounted upon, the rings 39.

In the drawin s I have disclosed as the preferred form, the constructionwherein the flange 43 is brazed upon the rings 39.

The axle block 22 is normally held in concentric relation to the plates28 and rings 39 by springs 44, 45 and 46. The springs 44 and 45 areguided by loose pins 47 The pins 47 are loosely mounted in passages 48formed in horizontal extensions 49 on the axle block 22. The outer endsof the springs 44 and 45 are held in cups 50. The pins 47 are shortenedto permit a maximum vertical vibration of the block 22 between the upperand lower slide plates 51 against which thecups 50 rest, and throughperforations centrally disposed in which, the arms extend, as shownbest'in Fig. 3 of the drawings. The springs 46 infold pins 52, which arelaterally extended fromthe block 22, as shown best in Fig. 5 of thedrawings, and bear upon the end 53 of the hub block and the slide plates54. The slide plates 54 are centrally pierced to provide passages forthe arms 36. As seen in Figs. 2, 3 and 8, the plates 51 and 54 areguided in their movement on thehollow seg ments by the edges of theplates 28. c The springs 44, 45 and 46 are selected and arranged withreference to the work performed thereby. The major portion of the loadbeing carried by the springs 45, they are constructed from a relativelystronger material. The springs 44 and 45 are arranged in sets of four,while thesprings 46 are arranged in sets of two, the latter havingrelatively lighter work in keeping the hub and wheel connected therewithin working position.

By the arrangement of springs, the circular portion of the hub formed inpart by the plates 28, members 29 and 30, and rings 39, is permitted tovibrate or float about the hub block, to yield to the shocks of theroad,

whether applied to move said hub upward,

downward, rearward, or forward, or' in any other dlrectlons intermediatethose named,

. said springs always operating, when unobstructed, to return said hubto its normal position, where the center of said block is the center ofsaid hub. Further, it will be understoodv that, while the connectingsprings permit the hub to rotate about its center to a limited degree,the normal operative position of said hub is that wherein the plates 54are perpendicular to the arms 35 and 36. It will also be understood thatwhen a vehicle having wheels as herewith shown and de scribed, iscarrying a load, the center of the axle block 22 and the axle mountedtherein are not coincident with the center of the hub ternal wheel bymeans of a train of bearing rollers 55. The rollers are each providedwith a felly rim 56. The rim 56 is supported by double-web disks 57. Thedisks 57 are united by suitable rivets 58, and are centrally perforatedto fit an internally-threaded tube 59. The rims 56 are shaped to fit thechannel of the track rings 39 and 60, the latter being rigidly mountedupon the felly. rim 61 of the above-mentioned wheel. The disks 57 arerigidlyconnected to the rims 56 by providing indents 62 in the edges ofsaid rims, and striking small tabs 63 into said indents, in theoperation of uniting said rims and webs. i

The rollers constructed as above described are connected in pairs, beingeach clamped rigidly'to the tubes 59 by bolts 64. The tubes 59 havethreaded thereon spacing collars 65 and a sleeve 66. Under the heads ofthe bolts 64 are spaced washers 67. This construction is best seen inthe upper half of Fig. 2 of the drawings. lVhen the bolts 64 aretightened, the rollers held thereby operate as units, the combinedsleeve 66 and collars 65 in each pair forming spacing membearings forsaid sleeves and shaft partly;

formed thereby. In this manner, the rollers 55 are accurately andreadily spaced apart. The rims 56 of said rollers are accurately turnedto form a neat fit between the track rings 39 and 60. The wheel to whichthe rings 60 are rigidly connected revolves around the hub abovedescribed and about the rollers 55. The felly rim 61 of said wheelrigidly supports said rings 60 and a felly 71. To the felly thusprovided are secured, by means of bolts 72," tire clamping plates '73,

. which in service hold the solid'tire 74.

The wheel is faced or protected from dust, at the outer side, byasheet-metal disk 75. A central opening formed therein, opposite the endof the axle 20, is covered by a cap76. The inside of the wheel is facedwith a' similar disk 77, a central opening wherein is covered by slidingplates 78 and 79. The plates 7 8 are arranged to slideverticallyinguides provided by a frame 80. A similar frame is provided on the plate78 to permit the plate 7 9 which closely infolds the axle 20, to slidehorizontally on said plate 78.
